Many of the vintage vehicles have few miles on the odometer, with at least 50 having less than 20 miles, and two cars, a 1959 Bel Air and a 1960 Corvair Monza, having just one mile on the odometer.

The oldest car in the two-day auction dates back to 1958, while the newest is a 1980 Monza with nine miles on it.

"To find this many new, old vehicles is unheard of," said Yvette VanDerBrink, the auctioneer coordinating the event, the AP reported. "It's like a white buffalo."

Among the most valuable vehicles on the block is the rare Chevy Cameo pickup, which reportedly could bring in as much as six figures from collectors.

The cars will be sold on the block in as-is condition, and will be available to bidders both in person and online.

According to VanDerBrink, preparations for the auction began in June and organizers have already received inquiries from car collectors from as far away as Singapore, Iceland, and Brazil.

"This kind of stuff is absolutely the rarest of the rare," Mark Gessler, president of the Historic Vehicle Association in Gaithersburg, Md., told the AP. "You can see plenty of cars that have been restored. We want to ensure that we're celebrating the original craftsmanship, the original technique. It's a touchstone of our past."

Retiring from the dealership in 1996, Ray and his wife, Mildred, decided to sell the vehicles so others could enjoy the cars as much as they loved to collect them over the years, the former car salesman's daughter Jeannie Stillwell said.

According to Stillwell, her father rarely sold cars or pickups after they were at the dealership for more than 12 months, believing the car's value would depreciate over time.

"I believe that Dad's sales approach reflected his personal style," Stillwell said. "He is a very honest, straightforward man who was focused on giving his customers the best price right from the start. Negotiating over price was a waste of time, and so that element of the sale was eliminated."

Lambrecht, a U.S. Army veteran who is now 95 years old, is reportedly in declining health.
